I ride bikes every where as a kid , then stopped, as you do. Started in May strugling to do 10 km on a mountain bike at 14 kmh average, I built the average to 27 kmh over 46km. I've just bought a cracking second hand Dolan and the average has gone upto just shy of 30kmh average over 20 kmh and the longest ride on Sunday was 60 km at 28.4 kmh average followed by a 10 km recory ride at 23 kmh! I'm lovin it. Interval training tomorrow and Friday to push the average speed and a recovery ride in between. I'm looking to push harder on Sunday to crack 80-100 km . My ass is on fire mind so I guess the saddle might need to be changed
